The Impact of Trawling on Nitrogen Removal through Sediment Denitrification in Western Moreton Bay. Nutrient enrichment of coastal waters is a national problem requiring urgent action. Sediment denitrification is one of the few natural processes capable of counteracting the process of eutrophication. Although trawling is undertaken in coastal water bodies around Australia the impact on sediment denitrification and the nitrogen budgets of coastal systems has never been considered. Many hundred's of millions of dollars are likely to be spent over the next ten years on the management of nitrogen enrichment of Australia's coastal waters. This study will quantify the impact of trawling on sediment denitrification; information which is critical for the efficient allocation of management resources.

拖网对莫尔顿湾西部沉积物反硝化作用氮去除的影响。沿海沃茨的富营养化是一个需要采取紧急行动的全国性问题。沉积物反硝化作用是能够抵消富营养化过程的少数自然过程之一。虽然在澳大利亚周围的沿海水体进行拖网捕捞，但从未考虑过对沉积物反硝化作用和沿海系统氮收支的影响。在未来十年内，可能会花费数亿美元用于管理澳大利亚沿海沃茨的氮富集。这项研究将量化拖网对沉积物反硝化作用的影响，这是管理资源的有效分配的关键信息。
